A McKinney middle school teacher is being held in the Collin County jail on suspicion of having an improper relationship between a teacher and a student.

Sharon Lynn Hoskison, 39, was booked into jail Monday afternoon and is being held on a $200,000 bond. The student is 17 years old.

McKinney ISD officials sent a letter to parents at Evans Middle School, where Hoskison teaches eighth grade social studies and history. The letter states that Hoskison was placed on administrative leave pending the outcome of an investigation by McKinney ISD and McKinney police.

"Please know that we take these matters very seriously, and student safety is our top priority," stated the letter from Evans Principal Todd Young.

Further details about the charge against her weren't immediately available. McKinney police declined to comment.
